Answer:
fish tank is 14.87 ≈ 15 inches tall.
Step-by-step explanation:
Given : A rectangular fish tank contains 3,240 cubic inches of water. The dimensions of the base of the fish tank are 12 inches x 18 inches.
To find : How tall is the fish tank.
Solution : We have given that volume of fish tank = 3240 cubic inches.
Length of tank = 12 inches.
Width of tank = 18 inches .
Volume of rectangular tank = length * width * height
3240 = 12 * 18* height .
3240 = 216 * height.
On dividing both side by 216 and switching the sides .
Height = .
Height = 14.87 inches
Therefore, fish tank is 14.87 ≈ 15 inches tall.
By substituting x = 2 into the function f(x) = 2(x)² + 5√(x + 2) and simplifying the equation, the resulting value of f(2) is calculated to be 18.
For the given function f(x) = 2(x)² + 5√(x + 2), we are asked to find the value of f(2). To find this, first substitute x = 2 into the function. So, the calculation becomes
f(2) = 2 * (2)² + 5 * √(2 + 2)
simplifying this equation, we get:
f(2) = 2 * 4 + 5 * √4 = 8 + 5 * 2 = 8 + 10 = 18
So, f(2) = 18
